How to UploadFile to web server without creating a file?

I have to upload dynamically created data file to web server. One way to do that is to create a temporary file dump dat开发者_开发知识库a to that file, and then use WebClient.UploadFile to do work. But how to do that without creating a file?

You can call WebClient.UploadData, which takes a byte array, or UploadString, which takes a string.
